# How-To:
01 - Preheat oven to 350°F (175°C). Grease and line three 8-inch round cake pans with parchment paper.
02 - In a medium bowl, whisk together the flour, baking powder, baking soda, and salt.
03 - In a large bowl, beat the softened butter, vegetable oil, packed brown sugar, and granulated sugar until light and fluffy, about 3 minutes.
04 - Add eggs one at a time, beating well after each. Mix in vanilla extract and butter flavoring.
05 - Add the dry ingredients in three additions, alternating with the buttermilk and cream soda, beginning and ending with the dry ingredients. Mix just until combined.
06 - Divide the batter evenly among the prepared cake pans. Smooth the tops with a spatula.
07 - Bake for 24 to 28 minutes, or until a toothpick inserted into the center comes out clean.
08 - Cool cakes in the pans for 10 minutes. Remove cakes from pans and transfer to wire racks to cool completely.
09 - Beat softened butter and brown sugar in a bowl until fluffy. Gradually mix in confectioners’ sugar. Add heavy cream, vanilla, butter flavoring, and salt. Beat until light and spreadable, adding extra cream if needed for consistency.
10 - In a small saucepan, melt butter over medium heat. Stir in brown sugar and cook for 2 minutes, stirring constantly. Slowly pour in heavy cream and salt. Simmer for 3 to 4 minutes until thickened. Remove from heat and stir in vanilla extract. Allow sauce to cool to room temperature.
11 - Level cake layers if necessary. Place the first layer on a serving plate and spread with frosting. Repeat with remaining layers.
12 - Frost the top and sides of the cake, swirling the frosting to create a rustic appearance. Drizzle butterscotch sauce over the top, letting it drip down the sides. Finish with gold sprinkles and crushed butterscotch candies if desired.
